AI strength plans: Fitbod vs Alpha Progression vs Gravl

Choosing software that plans the next lift

Fitbod, Alpha Progression and Gravl help decide what a strength workout contains and what weight or repetitions to attempt next. Their intelligence is expressed through programming and logged performance, not simply a conversational coach. The main buying decision is how much of the routine should stay stable, what should adapt and how closely the app follows the equipment available.

Fitbod

Fitbod builds resistance-training sessions from goals, experience, available equipment, workout history and estimated recovery. A user can change the duration or equipment context rather than rewrite every exercise manually. Exercise preferences, substitutions and variability settings influence what comes back in later sessions, making the planner useful when the circumstances of training change.

Its adaptation is tied to a record of completed sets, repetitions and weights. Estimated Strength is recalculated from logged work; Max Effort Days provide another calibration input. A gap in logging can lower the estimate, and a longer break can reduce recommended loads. Those numbers are software estimates, so a falling app score should not automatically be read as a measured loss of physical ability.

Fitbod also supplies exercise demonstrations and progress records, and previously generated workouts can be completed offline. It fits someone who wants the app to produce the next session from current context. The feedback loop is most useful when actual substitutions and completed work are recorded, because a plan based on what was prescribed is different from one based on what was done.

Alpha Progression

Alpha Progression centers on an editable program whose exercise structure can remain consistent while its working-set targets evolve. Pro can generate a complete plan or a single workout using goals, experience, training frequency, duration, equipment and muscle priorities. Users can also build the routine themselves and apply Pro's progression guidance to it.

Weight and repetition recommendations use earlier performance, sets already completed in the current session and available weight increments. If the next dumbbell is too large a step, the system can recommend more repetitions first. Optional RIR targets, periodization and deloads add control for someone who wants a recognizable training cycle rather than a wholly different session each day.

The permanent free version is a meaningful manual tracker: own plans, unlimited logging, exercise videos, measurements and CSV export remain available. Generation, recommendations and charts require Pro. An important boundary is that starting generated workouts still requires an active Pro subscription after cancellation takes effect. Alpha Progression fits lifters who want a stable plan, precise targets and a clear distinction between free tracking and paid programming.

Gravl

Gravl builds workouts around a gym's equipment, the weekly schedule and training history. Its recovery-based split helps choose muscle groups, while exercise substitutions recalculate the planned sets, repetitions and weights. A user can move between gym profiles rather than pretend every machine and available load is identical everywhere.

Its load recommendations respond to exertion feedback, recent performance and the exercise's position in the session. Machine strength records are gym-specific because resistance can differ between machines; free-weight records follow a different continuity model. The app can also explain the basis of a recommended weight, helping a user see the record behind today's target.

Gravl's AI import workflow is a separate advantage: a routine in a link, photograph or PDF can become a structured workout that is ready to log. Watch support includes Apple Watch, Wear OS and Garmin. It fits people combining routines from elsewhere with adaptive guidance, or moving between different training locations. Its introductory free workouts are finite and should not be confused with Alpha Progression's permanent manual tracker.

Stable program versus adaptive session

Alpha Progression is the strongest fit here when repeating an editable program structure is the priority and progression should happen within its sets. Fitbod emphasizes producing sessions from recovery, equipment and personal history, with exercise variability under user control. Gravl combines recovery-aware planning with gym settings, substitutions and imported routines. These are programming preferences, not a demonstrated ranking of strength outcomes. A lifter who wants familiar exercises every week may choose differently from one who frequently changes training locations.

Equipment changes and useful feedback

All three use equipment and logged performance, but the handling differs. Alpha Progression explicitly constrains set guidance to the weights available in the gym. Fitbod regenerates around equipment context and learns from exercise choices and performance. Gravl distinguishes machine records by gym and explains targets using exertion and session order. Gravl's imports are particularly relevant when the starting point is a coach's PDF; Alpha Progression's own-plan editor is relevant when the starting point is a routine the user wants to build directly.

Free access and the charged period

Alpha Progression offers ongoing free manual logging, with Pro required for generation and progression. Fitbod's introductory access is a trial. Gravl's official support allows three introductory workouts for most users, five in South America, then asks for a subscription. Annual totals in the table are annual charges, not monthly installments. Gravl's US store contains several yearly offers, so its applicable annual renewal is left unconfirmed rather than choosing the cheapest listing as a universal rate.

Which planner fits your lifting routine?

Choose Fitbod for sessions that adapt to the training context. Choose Alpha Progression for a stable, editable program and working-set progression. Choose Gravl for gym-aware records and importing routines into an adaptive tracker. The comparison evaluates planning software; it does not claim hands-on gains, a form diagnosis or a substitute for individual clinical advice.
